TO ALL WHOM I1 MAY CONCERN lic it known that LLEWIS T. EWEL., ci Springville. in the county of Eric, and in the State of New York, have invented ce1-minnen? and useful ilnprovclnfnts in' Corn Shellcrsand do hereby declare that the followingiis a full, clear, and exact description tl1ereo f,referenc'e boing had to the accompanying drawings, and to thcnletters et' reference marked thereon.

The nature of my invention consists in the combination and nrrangcmentof two or more grooved or toothed concavo'wheels, one or more of said wncels'heingl less concave than the others; and a grooved concave 'spring n board, lin which the depth of the concavity gradually decreases from the top to the bottom; and inleaving open-4 'ings in the slieliing-v'lieeis, which are'mzxdc by leaving out one or rnorc of the shelling teeth, for the purpose of' allowing the corn to he incre' readily drawn into the machine, said openings being so arranged' on the several wheels that when tito first opening is placed in the proper, position to receive the corn when introduced'hwhici position is obtained hy raising the handle up to its highest point, the ,openings in the succeeding wheels will be in the proper position tccatch the end of the ear as it cornes down; also, in .so forming o r shaping; the shelling teeth that, in the operation of shelling, they will strike between 'the grains and force themo` without` scraping or'rubbing. It further consists in a weighted bar or lever, when so arrangedlthat the fulcrum may be changed, s0 that by the same weight different degrees ci' pressure maybe given to the spring board. i

In the several figures, like letters represent similar-.parts in each. Figure l represents a section through a fragment of thelower wheeh Figure 2, a perspective view of the machine complete. .l v 'Figure 3, aside elevation of one of the upper shelling-wheels, showing the arranglnent of the shelling teeth and teeth for gearing.

Figure -i-4 is an inside view of the working parts of the machine, and a vertical section through the shelling wheels,`showing the; shape of the shelling teeth and gearing.

Figure 5 represents frontview of the spring boord; and i Figure 6, a perspective view. i' i l A A is the box for-holding the shelling-wheels v'and spring board.. E, the bench to which -it is fastened. C,

a post, forming part of the boit; it is fastened tc itlie bench by the wedge or pin D. H is the weighted lever; v

its fulcrum is changed. by changing the position of the piece I, and placing'the pin K in either of the apertures J L, or the one between them, by which means the pressure of the spring hoard against the corn may be either increased or diminished without changing the weight on the end cf the lever. G represents the upper shelling :ind spurwheel, and G" the lower one; they receive their motion hytiie handle F, 'which is attached to one of i the shelling-heels The p'izion-whee-l N, gear'il'ig inte each of the shelling-wheels, causes the iower-one to," revolve in the some direct-ion :Ls the upper one. The shelling-wheels have s. double setoi" wedgeshaped teeth,

for shelling, the position and sha-pe oiwhich, and arrangement, :tre clearly shown in tigo. 3 and 4. The upper wheel is vmade more concave than the lower one, as will be readily seen-by reference to gs. 1 and 3. P`represents .the spring board; it is held up against thevcorn by the upper end of the lever H, which is made so as to tit linto the opening Q, made to receive it,- lR B, and E, E represent parte of the spring board which are cut away to allow the wheels G and G to be brought nearer to M hi, in gf'i., represent rubber spiings, w h-ich can be used to increase the pressure of the spring 'boe-rd if necessary, is an opening in the post `@,irrto which the pinion N is tted. The concave surface of the spring/hoard is made deeper at the ltop than at the betteln, the depth of which gradually diminishes from the top to the bottoni, and which is cleerljshown in iig. 6.

What I claim as'my invention, and desire to secure by VI e'tters Patent, is

1. The combination ot'two or more concave wheels, similar to G and G', when one er more of said wheels are made with the toothed concave surfaces deeper then` the others, substsntiaiiy es described.

2, The weighted lever H, provided with the movable piece piu K, and apertures and L, or 'the equivalent thereof, substantially' as and for thc purposes described; and in combination therewith 1 claim the spring hoard when constructed as described.v v r l 3. .I also c laim Vthe shape and general arrangement of the wheels G and G', b v which I combine in one the shelling and gearing teeth;
